I would prefer selecting bounties to work like decoding engrams.

I would like to put my cursor over the leftmost bounty (that I want). Then when I accept it, it is removed from the list and the next available bounties move one slot to the left.

Sort the bounties with available bounties to the left of unavailable.

Now that I have large enough slots, I just accept them all. I go to orbit and then prioritise which bounties I do and where.

So my ideal, least work way of doing this* would be: move cursor over leftmost bounty, press [X] repeatedly until all bounties accepted.

* A get-all-available button would be better but rapid [X] presses aren't too bad.
